Embodiment 1
[0016] An automatic irrigator with a humidity detection device, including a nozzle, a casing, a controller, a solenoid valve, a water inlet, a detection rod, and a hygrometer, and is characterized in that: the nozzle is installed on the upper part of the casing; the controller is installed on the left side of the casing position; the water inlet is connected to the right side of the casing; the solenoid valve is installed at the front of the water inlet; the detection rod is embedded in the lower part of the casing; the humidity sensitive resistor is installed inside the detection rod.
[0017] The invention solves the problem that the general automatic irrigation device can only irrigate regularly and quantitatively, but cannot form effective feedback by detecting soil humidity. By detecting soil moisture in real time, the most effective irrigation is performed at the optimum moisture point.
Embodiment 2
[0019] The casing of the present invention adopts a cylindrical shape, the detection rod adopts a conical and cylindrical shape, and the nozzle is in the shape of a truncated cone. Such design makes the present invention close to the current existing irrigation appliances to the greatest extent. On the one hand, it is easy to be accepted by people psychologically, and on the other hand, the existing parts can be fully utilized, which effectively reduces the cost.
[0020] In actual use, when the detection rod of the present invention is inserted into the soil, the controller starts to control the humidity sampling through the humidity sensitive resistor and calculates continuously. When the humidity value reaches the specified value, the controller controls the solenoid valve to open, and the water flows through The water inlet enters the nozzle, and then sprays out from the nozzle to reach the root system of the crop.
[0021] In this way, our irrigation is based on actual s...
